| 中文摘要: |
| 对隔振橡胶材料的单轴拉伸应力松弛试验数据进行归一化处理，应用Prony级数模型对其应力松弛试验数据进行拟合，获得对应的粘弹本构参数。将表征粘弹特性的Prony级数因子引入Ogden超弹本构方程，获得隔振橡胶材料基于时间效应的本构方程，进而分析单轴拉伸、双轴拉伸和平面拉伸模式的蠕变特性，最后采用沙漏弹簧进行蠕变仿真与试验验证。该蠕变仿真预测方法为隔振橡胶材料的粘弹试验、蠕变计算和工程应用提供一种新思路。 |
| 英文摘要: |
| The stress relaxation test data of damping rubber materials were normalized，and the corresponding viscoelastic constitutive parameters were obtained by fitting the stress relaxation test data with Prony series model.The Prony series factor representing the viscoelastic characteristics was introduced into the Ogden hyperelastic constitutive equation to obtain the constitutive equation of damping rubber material based on time effect，and then the creep characteristics of uniaxial tension, biaxial tension and plane tension
modes were analyzed.Finally，the creep simulation and test verification using hourglass spring were carried out.This creep simulation prediction method could provide a new idea for viscoelastic experiment，creep calculation and engineering application of damping rubber materials. |
